Family of Medium Tactical Vehicles

The FMTV's origins trace back to a U.S. Army Training and Doctrine Command (TRADOC) requirements document issued in 1983 for a Medium Tactical Truck (MTT), the intended replacement for the in-service 2.5-ton truck. In July 1984, a program to look at a future 5-ton truck procurement to replace in-service 2.5- and 5-ton trucks began. Cost analysis demonstrated that the procurement should be for both 2.5- and 5-ton trucks. In October 1984, the FMTV formally began as a program. The request for proposals (RFP) for FMTV was released in 1988. At this time it was expected that around 120,000 trucks would be ordered, over three five-year contracts. In August 2007, Armor Holdings was acquired by BAE Systems. The United States Army had intended that two variants of the Future Tactical Truck System (FTTS) would eventually replace virtually all of its tactical wheeled vehicle fleet, including the FMTV. The FTTS never materialized. However, along with inputs from other efforts, the FTTS continues to be used to define requirements for future United States Army trucks. In May 2009, BAE Systems, Navistar Defense and Oshkosh Defense each submitted proposals for the FMTV A1P2 competitive rebuy program to the U.S. Army's Tank-Automotive and Armaments Command (TACOM) Life Cycle Management Command. In August 2009, the United States Army announced that Oshkosh Defense had been awarded the FMTV A1P2 rebuy production contract. The award was protested by both BAE Systems and Navistar. The FMTV A1P2 rebuy was awarded as a five-year 'build-to-print' requirements-type award, that at award, allowed the U.S. government to order from 0 up to 12,415 trucks and 10,926 trailers to 2014. Some FMTV variants were excluded from the rebuy competition. Those excluded include specialist FMTV variants such as HIMARS, Patriot, MEADS and LVAD, plus all the armored cabs developed by BAE Systems. At this time Oshkosh confirmed that since deliveries started in 2010, the company had received orders for over 24,500 FMTV trucks and 11,400 FMTV trailers. On 21 September 2017, the U.S. Army made an administrative modification to the FMTV A1P2 requirements contract with Oshkosh, to establish the eighth, ninth and tenth Order Years' pricing under the contract, at an estimated value of $466 million. This administrative modification authorizes future orders under the FMTV A1P2 contract to August 2019. This contract extension will close out production of the FMTV A1P2. In November 2017, Oshkosh announced the delivery of the 25,000th FMTV truck to the US Army. In June 2018, Oshkosh announced that the U.S. Army Contracting Command had placed four additional orders, for a total of 771 FMTV A1P2s, valued at $159.6 million. In February 2019, the U.S. Army Tank-automotive and Armaments Command (TACOM) Life Cycle Management Command (LCMC) placed orders with Oshkosh for a further 354 FMTV A1P2 trucks and trailers, at a value of $75 million. By February 2019, Oshkosh had delivered more than 38,100 FMTVs since the award of the FMTV A1P2 contract. In June 2019, the US Department of Defence awarded Oshkosh a $320,000,000 modification to domestic and Foreign Military Sales (Argentina, Djibouti, Iraq, Lebanon, Romania) contract, for procurement of Family of Medium Tactical Vehicle variants. The estimated completion date is August 2021. In August 2021, Oshkosh confirmed that the company had produced over 40,500 A1P2 trucks and trailers. FMTVs are currently being reset at the Red River Army Depot on return from deployed operations. Current projections are for a recapitalization program to begin in 2020/2021. ==Description ==

The 2.5-ton (4×4) FMTV is designated as the Light Medium Tactical Vehicle (LMTV). The 5-ton (6×6) is designated the Medium Tactical Vehicle (MTV). In a move away from previous United States Army designs, a cab over engine (COE) design was selected for the FMTV, as while the US Army did not specify this configuration, given the Cold War situation prevailing at the time it had indicated that overall length for shipboard transport was a consideration. The design of the FMTV has never remained static and to further increase reliability, user-friendliness, and operational flexibility, detailed refinements/upgrades have continued throughout FMTVs production run. The FMTV is built around a conventional bolted / Huck-bolted, cold-formed C-section chassis, with bolted-in tubular cross-members. The high-grade 758 MPa steel used is sourced from Sweden. LMTV variants can be fitted with a DP-10J winch with an 11,000 lb. line pull. MTV variants use a DP-515 winch with a 15,500 lbs. line pull. Current production FMTV A1P2s are powered by a 2007 Environmental Protection Agency (EPA) emissions-compliant 7.2-liter six-cylinder Caterpillar C7 diesel engine, producing 275 hp and 860 Lb.-Ft. torque in LMTV variants and 330 hp and 860 Lb-Ft.torque in MTV variants. FMTV A1Rs have a 2004 EPA emissions compliant version of the same engine with the same power output. FMTV A1 variants have an earlier 1998 EPA emissions-compliant version of this engine, the 3126 ATAAC, which produced 275 hp at 2,400 rpm and 815 Lb.-Ft.torque at 1,600 rpm in LMTV variants, and 330 hp and 850 Lb.-Ft.torque in MTV variants. A 6.6-liter derivative of this engine, the 3116 ATAAC, was fitted to FMTV A0 models where it produced 225 hp and 735 Lb.-Ft. torque in LMTV variants, and 290 hp at 2,600 rpm and 860 Lb.-Ft. torque in MTV variants. The Allison 3070 SP seven-speed transmission fitted to A1P2 and A1R FMTVs evolved with the FMTV, its A1 designation being MD 3070 PT, its A0 designation being MD-D7. This has an integral single-speed transfer case. All-wheel drive is full-time, with a 30/70 percent front/rear torque split for on-road driving, and a 50/50 percent split for off-road driving. All FMTV models are fitted with Meritor beam axles, with ratings and specifications evolving as the FMTV has developed. Suspension is by a combination of parabolic tapered leaf springs, inverted on the MTV rear bogie, shock absorbers, and an anti-roll bar for the rear axle/bogie. Two cargo trailers are part of the Family of Medium Tactical Vehicles (FMTV). The M1082 single-axle trailer is used with the LMTV cargo truck. The M1095 twin-axle trailer is used with the MTV cargo truck. Both trailers have payloads that match that of the towing truck, and they share many components, including axles, with the towing truck. ==Variants==

Current and recent operational scenarios call for logistic trucks of the FMTV type to have at least the option of cab armoring. When it entered production, armoring was not considered an option for the FMTV. The first protection solution for the FMTV was not in answer to such scenarios, but was developed by Stewart & Stevenson and O'Gara-Hess & Eisenhardt Armoring Company (OHE). Called the Crew Protected Cab, it was specifically for the HIMARS variant and offered flash and Foreign Object Debris (FOD) protection during launch. Designs followed for an Enhanced Crew Protected Cab, and later an Armor Protected Cab, each adding more ballistic capability against direct fire, artillery burst and mines. In answer to demands for greater crew protection, BAE Systems developed the Low Signature Armored Cab (LSAC) for all variants of the FMTV. The LSAC replaced the standard FMTV cab, with which it shares internals, in a remove and replace operation. To meet the US Army's current Long Term Armor Strategy (LTAS) for armored cabs, BAE Systems developed the LTAS cab for the FMTV. BAE Systems produced over 9,000 LTAS cabs for the FMTV A1P2 variant. All Oshkosh FMTV vehicles include the company's own LTAS-compliant armor solution. The Caiman Mine Resistant Ambush Protected (MRAP) vehicle is based on the MTV A1R platform. The United States Marines placed an initial order with the then Armor Holdings for 1,170 Caiman in July 2007. 2,868 Caiman were ordered, with deliveries completed in November 2008. In winter 2010, BAE Systems unveiled the Caiman MultiTerrain Vehicle (MTV) at AUSA. The Caiman MTV is a modified version of the base Caiman, that features a revised driveline, a new chassis and upgraded fully independent suspension. BAE Systems received contracts to upgrade 2,071 (1,700 + 371) Caiman to Caiman MTV standard. These upgrades were completed in Q1/Q2 2014. Post-Afghanistan, no Caiman MRAPs have been retained by U.S. armed forces. Some have been transferred to U.S. law enforcement agencies. Others have been offered as Excess Defense Articles (EDA) to Iraq, Jordan, Nigeria and the United Arab Emirates (UAE). In 2008, BAE Systems unveiled the Caiman Light (CLT), a five-man 4×4 version of the Caiman. To meet the Iraqi Light Armored Vehicle Requirement (ILAV), BAE Systems offered a fully armored LMTV on which the LSAC cab was extended rearwards, into a troop carrying body. Neither of these proposals entered production. ==Prototype and developmental FMTVs==

• Working with Multidrive an LMTV was integrated with a powered companion trailer to produce a C-130 Hercules transportable vehicle with a 15,000 kg payload. • The FMTV Hybrid Hydraulic Vehicle (HHV) was selected as the test platform for the development of a hybrid hydraulic propulsion system. • The FMTV was selected as the platform to demonstrate that a 155 mm M777 howitzer and prime mover could, for the first time, be deployed in the same C-130 aircraft. • Stewart & Stevenson produced five hybrid electric FMTVs, each tailored for a specific application. • Stewart & Stevenson developed an 11-ton FMTV A1 demonstrator to demonstrate the growth potential of the FMTV family and C4ISR integration potential, via technology insertions, while retaining maximum commonality with the current FMTV fleet. A second vehicle with a tilt-type loadbed was also developed as part of the aborted Future Tactical Truck System (FTTS) requirement. A 13-ton demonstrator then followed. • Stewart & Stevenson developed a 13-ton Medium Tactical Truck Demonstrator (MTTD) that incorporated many of the technologies and capabilities that the Army then envisioned for its future trucks. • A number of 8×8 FMTVs have also been developed, these including examples for Australia's Land 121 (awarded to Rheinmetall MAN Military Vehicles (RMMV)), a 13-ton demonstrator with a load handling system, and a pair of chassis as part of the Future Tactical Truck System (FTTS) undertaking. • Oshkosh Corporation unveiled the FMTV Enhanced Protection & Mobility Demonstrator (EPMD) during 2012. The FMTV EPMD is fitted with Oshkosh's TAK-4 independent suspension system and a custom-fitted Oshkosh Underbody Improvement Kit (UIK). • To help inform the U.S. Army's FMTV A2 acquisition strategy and performance upgrade requirements Nevada Automotive Test Center was awarded a contract in 2014 to manufacture and test two FMTV Technology Demonstrators. These are based on government-supplied M1157 A1P2 10-ton Dump chassis produced by Oshkosh, but upgraded by NATC. Testing concluded in February 2016. ==FMTV A2==

Early in 2014, the U.S. Army's Program Executive Officer for Combat Support and Combat Service Support (CS CSS) suggested that the Army would be seeking a new medium truck family in the mid-2020s. In October 2016 the U.S. Army solicited proposals for the FMTV A2 rebuy competition. The FMTV A2 request for proposals (RfP) stated the program would seek "to integrate higher capacity suspension, wheels, and tires; integrate underbody protection; increase engine power; integrate higher capacity alternator; integrate data bus upgrade; and integrate safety enhancements". The winner of the contract would be asked to integrate such upgrades; build the vehicles, trailers, and kits; and provide program, maintenance, and logistics support. According to the RfP, the FMTV A2 contract is expected to cover five ordering years with two additional one-year option periods for a potential total of 2,400 vehicles if all options are exercise. In a subsequent statement, an Army spokesman said the RfP "includes an estimated quantity of approximately 2,400 new production vehicles. However, the actual quantities in any future award are undetermined and will depend on proposed pricing for this quantity, army requirements, and available funding." In May 2017, Oshkosh submitted a proposal in response to the RfP for the Family of Medium Tactical Vehicles (FMTV) A2 production effort. At this point, the U.S. Army anticipated a contract award announcement in the second quarter of fiscal year 2018 and stated that the next generation FMTV A2 would comprise 16 models and three trailers. Following the FMTV A2 award, Oshkosh initially built and delivered vehicles in support of Production Verification Testing (PVT), Live Fire Testing (LFT) and logistics development. In August 2021, it was announced by Oshkosh that the Army's Tank-Automotive and Armaments Command (TACOM) Life Cycle Management Command (LCMC) had awarded the company a $152 million delivery order for 541 FMTV A2. The Army is expected to begin fielding the A2 FMTV variant in June 2023.{{cite web |url=https://oshkoshdefense.com/oshkosh-defense-receives-order-for-fmtv-a2-as-fmtv-a1p2-production-begins-to-ramp-down/ FMTV A2 variants are: • M1078A2 LMTV cargo, CARGO • M1079A2 LMTV Van TRUCK, VAN • M1080A2 LMTV Chassis CHASSIS, TRUCK • M1082 Trailer TRAILER, Cargo, LMTV • M1083A2 MTV Cargo TRUCK, CARGO • M1084A2 MTV Cargo with MHE TRUCK, CARGO • M1085A2 MTV Cargo LWB TRUCK, CARGO • M1086A2 MTV LWB Cargo with MHE TRUCK, • M1087A2 MTV Expansible Van TRUCK, VAN • M1088A2 MTV Tractor TRUCK TRACTOR • M1089A2 MTV Wrecker TRUCK, WRECKER • M1092A2 MTV Chassis CHASSIS, TRUCK • M1095 Trailer TRAILER, Cargo, MTV XXXX-XX- • M1096A2 MTV LWB Chassis CHASSIS, TRUCK • M1147 Trailer, LHST TRAILER, FMTV Load Handling • M1148A2 LHS Truck TRUCK, MATERIALS HANDLING CONTAINER HOISTING • M1157A2 10 Ton Dump TRUCK, DUMP XXXX- • M1157A2 10 Ton Dump with winch TRUCK, DUMP • M1273A2 10 Ton Dump Chassis CHASSIS, ==Gallery==
